Programming Notes
|
|
=================
|
|
For details on how to setup a full-screen DirectDraw app, see the FullScreenMode
|
|
sample.
|
|
|
|
To adjust the gamma, first check to see if the device supports it. Call
|
|
IDirectDraw::GetCaps to check if DDCAPS2_PRIMARYGAMMA is set. If it is, then
|
|
you can set the gamma ramp by calling IDirectDrawGammaControl::SetGammaRamp.
|
|
|
|
For simplicity this sample creates a gamma ramp which is linear for all
|
|
color components. The ramp runs from 0 at index 0 linearly up to a user
|
|
defined number at index 255 for each of the color components. However, the ramp
|
|
does not need to be linear.
